The best way to fetch data from html based on css or html tags is to use NOKOGIRI gem.

Here is the process to achieve it:

$ sudo gem install nokogiri

# Open your controller

#Include open-uri & nokogiri

require ‘open-uri’

require ‘nokogiri’

class FetchController < ApplicationController

def index

doc = Nokogiri::HTML(open(‘kunalinfotech.net/company/about-us.html’))

doc.css(‘body,h1′).each do |link| @fetch = link.content

end

# Index.html.erb

<%= @fetch %>
